Abstract
A study was conducted to investigate ion chromatography (IC) for determining selenium species in groundwaters. Analytical speciation of selenium was investigated because the removal efficiencies of various processes for selenium removal (activated alumina in particular) depend on which species (Se IV or Se VI) is predominant in the groundwaters. In addition to investigating IC, the study aimed to determine a preservation technique for maintaining species integrity, and to analyze field samples taken from seleniferous regions to assess which of the two selenium species predominates.
